FRANCESCO LAMBERTI, OF GENOA, ITALY.

ROTARY MOTOR.

Application filed .Tune 30, 1910.

To all whom it may concern:

Be it known that I, FRANCESCO LAMBERTI, professor, a subject of the King of Italy, residing at 19 Via Palestro, Genoa, in the Kingdom of Italy, manufacturer, have invented a certain new and useful Centrifugal Expansion Rotatory Motor for an Expansible Fluid, of which the following is a specification.

This invention relates to improvements in i rotary motors.

The object of the invention is to provide a rotary motor in which the full power of the steam is utilized before the exhaust occurs.

The invention depends on two principles, one of which may be termed the principle of intercepted outlet turnstile and the other the principle of centrifugal expansion.7

Figures 1, 2, and 3 embody these principles and represent the hypothetical apparatus in longitudinal and transverse section. Fig. 4l is a longitudinal section of a rotary motor constructed in accordance with this invention. Fig. 5 is a transverse section of a portion of the apparatus. Fig. 6 is a longitudinal section of a portion of the apparatus. Fig. 7 is a transverse section taken yon the line 7-7 of Fig. 6. Fig.` 8 is a longitudinal section ofa slightly modified form of motor. Fig. 9 is a transverse section taken on the line 9 9 of Fig. 8. Fig. 10 is a longitudinal section of still another form. .Fig. 11

In the embodiment illustrated inFigs. l, 2, and 3, a receptacle R is mounted on a pivot A and an axle A. This axle A vforms a conduit between a pipe I-I and the recep tacle R and is designed to convey a fluid from a source not shown. The axle A is movably mounted in a bearing c and the pivot A in a bearing c. A canal F opens through the periphery of the receptacle R and may be of any suitable or desired length and is constructed substantially in the form of a flattened pipe. spiral formand fixed to the receptacleR with its inner end I ending in the opening or canal F. A plurality of diaphragms D are disposed successively in the canal F and are maintained in fixed position by arms o, xed to a rod J secured to a bracket K fidxedin the proximity of the interior end of Specication of Letters Patent.

the hole or canal F, and ending where the system turns at an angle d, see Fig. 3, at which point the diaphragm is disposed in proximity to the outer end of the canal which is near to the end of the tube I. Suppose, for example, that every diaphragm after having occupied the position above described and after the succeeding diaphragm D held fixed by the arm d began to operate1 the preceding diaphragm of the interior end of the hole or canal F disappears, it is evident that if I then introduce the operating fluid into the receptacle R upon the internal wheel, such fluid will cause the rotation of the system. In consequence of this rotation, the fluid will be introduced into the pipe T in successive quantities corresponding to the circumscribing volumes through the hole F by means of two consecutive diaphragme.

This manner of operation of the fluid comprises the principle of the intercepted outlet turnstile. The principle termed centrifugal expansion is dependent upon the action of the fluid in the pipe T after the beginning of the rotation of the system and of the fluid discharged from said pipe T through its other end into a receptacle suitably disposed to receive it. The diaphragms D and D and the successive diaphragme form means -suitable for intercepting the iuid outlet from the receptacle R and at the same time for regulating the fluid in the `pipe and inav be termed a distributer.

In Figs. 4 and 5 of the drawings is represented an industri-al application of theinvention with regard to the above named principles. In this embodiment a hollow axle A is shown similar to the axle of Figs. l, 2, and 3, and is incorporated with the r0- tary portion of the engine and is held by a bearing c which is provided with a stuffing box or other analogous device adapted to prevent the escape of the fluid around the axle. A pivot shaft A carries the turning part of the motor and is arranged in a bearing c in alinement with the axle A, the two bearings being carried by the supporting structure of the motor. A -pipeH connects the hollow axle A with the fluid channel not shown having a regulating valve V. The turning portion of the motor has a space S therein and is provided with a curb joint C containing a pipe t. This joint C is pref-V erably composed of two disks between which is fixed a spirally turned plate having an inlet I and an outlet U. Similar curbs C and C are spaced laterally from the curb C and any desired number of said curbs may be employed.

The curb C is provided with a distributing apparatus shown in detail and on an enlarged scale in Figs. 6 and 7, longitudinal and transverse sections of said apparatus being shown in these figures. This distributing apparatus comprises a box which turns jointly with the motor curbs and a fixed member F of cylindrical contour termed a nucleus. A plurality of diaphragms D are also arranged within the box. The box of this apparatus has substantially a cylindrical form on its outer face and its inner face cooperates with the cylindrical contour of the nucleus and the tubular space t. An annular cam G cooperates with the fixed member F and is provided with an inner cam face g which engages the nucleus. During the turning of the box the cam ring G frictionally engages the member F at the points f-f and the nucleus is held by the pivots p-p mounted in bearings supported by the member G and it is fixed by means of a rod y' which extends through the' member Gr and is provided with a stufiing box and is fixed to the motor in any suitable manner, preferably by means of arms K. lVithin the tubular space T one of the diaphragms D is continuously acting serving to form a transverse closure for said tubular space. These diaphragms D are forced outwardly as shown in Fig. 8 to form spaces @Z around the nucleus and when so projected to form closures for the tube t and they are afterward drawn into said spaces CZ to permit the member G to rotate. In these Figs. 6 and 7 are shown four diaphragme intercepting successively the space t during a quarter turn of the motor. Each pair of these diaphragms is connected by a rod or link Z and motion is imparted to said diaphragms by means of a cam b carried by a secondary axle L which turns with the box. This cam Z) operates upon rollers 7' which are fixed to the connecting links Z. The axle a and the cam o together with the rollers r are disposed within the nucleus which for this reason is made hollow. The diaphragms D may be projected by means of the cam on the inner face of the box if necessary but they are preferably actuated by the cam b in the manner above described. The box is preferably provided with two openings 0 and c the opening c affording a connection between the space S and one end of the tube t, while the opening c aords communication between the other end of the tube t and the pipe I of the curb C. R and R are designed to receive the fluid and precede the curbs C and C. Peripheral plates M and M incase the receivers R and R and a fixed casing N contains the turning portion of the motor and is provided with an outlet pipe P.

In the operation of this improved motor, the operating Huid from a suitable channel (not shown) enters through the valve V into the passage or pipe H and is conducted through the hollow axle A into the space S of the motor. From this space S the fluid passes through the opening c into the tube t and operates in the manner above described relative to the principle of the turnstile intercepted outlet. After passing through the pipe t the fiuid is discharged through an opening 0 onto the curb C and from there passes out through the outlet U and expands sucessively into the curb C and C, passing respectively through the receivers R, R between these curbs. In these curbs the fluid acts on the principle of the centrifugal expansion above described.

In the apparatus shown in Fig. l the passage of the Huid through the motor is clearly illustrated, the arrows indicating the passage from the outlet of one curb to the inlet of the succeeding curb and from the outermost curb C into the casing N and out through the outlet P therein into the atmosphere or any suitable receptacle into which it is desired to pass.

The operation of the diaphragm D is clearly illustrated in Figs. S and 9 in which the cavity or space CZ within the nucleus are arranged in such a manner that said diaphragm operates therein by means of the connecting links Z which pass through the nucleus and engage said diaphragms.

In Fig. 8 the inner face of the member Gr is provided with two tubular channels e and e which extend concentrically with the axle and are adapted to contain the fluid under different pressures. Such pressures may be obtained by placing the channels e and e in communication with the fluid under different pressure or by depressing the members G and F in such a manner that the fluid will pass out from i and enter between said members and pass into the channels e and e and be discharged into a space in which little pressure is exerted. For example, by discharging through the interior cavity of the nucleus and the rod y', which is also hollow. By means of suitable spaces ,7c and 7c formed in member Gr and communicating with the channels e and e respectively, and of conduits ZL and ZL which lead into the cavities Z of the member F, some of the operating fluid may be opportunely introduced into the cavity d and be discharged upon every pair of diaphragms to facilitate their motion. A hollow rod may be provided to lubricate the pivots p and p', the axle a and cam ZJ, the rods or links Z and the diaphragms respectively.

In Fig. all of the curbs C, C and C are provided With a distributing apparatus and the nucleus F, F and F are joined together in fixed relation by a rod j and the boxes G, G and Gr are connected With the curbs and the axle a; turning jointly With v the curbs carrying the cams b, b and b Which impart motion to the distributing diaphragms. This form of motor is similar to the one above described, except the operating Huid passes from the outlet of one curb to the inlet of the succeeding curb through the distributing apparatus.

When desired a number of pipes or tubes may be employed and in Fig. 11 the box G is shown to be adapted for use When tWo tubes t are employed.

From the foregoing description, taken in connection With the accompanying drawings, the construction and operation of the invention Will be readily understood Without requiring a more extended explanation.
